ASSESSING RESERVOIR QUALITY IN TIGHT OIL PLAYS WITH THE DOWNHOLE RESERVOIR PRODUCIBILITY INDEX (RPI)

Reservoir quality (RQ) of unconventional resources is influenced by the amount and type of organic matter in the formation. In gas-bearing shales, gas is typically stored and transported through organic pores in kerogen—thus, high quantity of kerogen typically leads to higher porosity/permeability and is considered a positive RQ indicator. In oil-bearing shales, mineral-hosted pores contribute significantly to hydrocarbon storage and transport, while kerogen and bitumen can trap fluids by adsorption and blocking pores—thus, high quantity of kerogen and bitumen can be considered a negative RQ indicator, emphasizing the need to differentiate types of organic matter in tight-oil formation evaluation. Here we present reservoir producibility index (RPI) for assessing tight-oil RQ using exclusively downhole logs. The index differentiates oil from kerogen and bitumen as being, respectively, positive and negative RQ indicators. The utility of the RPI is demonstrated in several examples, wherein zones identified as having the best RQ are found to be the most productive.
About the speaker: Paul Craddock is a Research Scientist at Schlumberger-Doll Research Center in Cambridge, Massachusetts, USA. His research addresses oilfield formation mineralogy and chemistry using infrared, X-ray, and nuclear spectroscopic methods: examples include core and cuttings mineral analysis, molecular-level characterization of organic matter in shale, and derivation of formation matrix properties for enhanced petrophysical interpretations. He received a BS degree in marine chemistry from University of Southampton, MS in geochemistry from University of Leeds, and PhD in chemical oceanography from Massachusetts Institute of Technology/Woods Hole Oceanographic Institution. Prior to joining Schlumberger in 2011, Paul was a postdoctoral scientist at University of Chicago studying metal isotope systematics in Earth and planetary materials.
Future Events: Additional 2017 events are in the planning stages. Check our chapter website soon for details.
President: Andrew E. Pomerantz is the Geochemistry Program Manager at Schlumberger-Doll Research. His research focuses on the development of novel techniques to characterize the chemical composition of kerogen and asphaltenes, including methods in mass spectrometry, X-ray spectroscopy, and infrared spectroscopy. That molecular information is used to understand fundamental physical and chemical processes in petroleum such as asphaltene compositional grading and storage and transport in shales. He graduated from Stanford University with a PhD in chemistry in 2005 and has co-authored 50 peer-reviewed publications.
Vice President: Ravinath Kausik K.V. is a Senior Research scientist at Schlumberger-Doll Research. At Schlumberger he has focused on the development of novel NMR and petrophysical techniques for porous media, especially unconventional gas and tight oil organic shale plays. He has developed new NMR pulse sequences and petrophysical workflows for better understanding various fractions of unconventional plays such as the stored gas, bitumen, producible oil, kerogen and bound water. He is also involved in the development of the next generation NMR relaxometry and diffusometry measurements for both laboratory and logging applications. He obtained a M.Sc. from IIT Madras, India and Ph.D. degree in physics from the University of Ulm, Germany. He worked as a postdoctoral fellow at the University of California, Santa Barbara before joining Schlumberger-Doll Research in 2009.
Secretary: Julie E. Kowan is a Geomechanics Consultant with over 11 years’ experience helping operators drill safer, more cost-effective wells and plan field development by reducing non-productive Time (NPT) due to wellbore instability and improving production. Julie has expertise in unconventional reservoirs, pore pressure prediction, stress constraint, wellbore stability, fracture permeability and compaction and is also skilled at summarizing complex scientific models into digestible reports. Prior to launching J. Kowan Consulting, LLC and joining HXR Drilling Services in June 2016, Julie was a Geomechanics Advisor at Baker Hughes from 2009 to April 2016. Before being promoted to Advisor, Julie held several other technical geomechanics positions at Baker Hughes and GeoMechanics International from 2005 to 2009. Julie earned a Master of Science in Geology from Brown University and a Bachelor of Science in Geology from Rutgers University.
Treasurer: Tancredi Botto is a Principal Research scientist at Schlumberger-Doll Research, where he has contributed to and initiated a number of research projects based on nuclear technologies. Among those, he has developed and field tested a novel deep-reading density imager based on naturally occurring cosmic rays. He is also involved in nuclear modeling and microwave sensor research. Tancredi holds a PhD from the Vrije Universiteit, Amsterdam (1999) and a M.Sc. from the University of Genoa, Italy. Prior to joining Schlumberger in 2005 he worked on experimental nuclear physics as a Research Scientist at the MIT Laboratory for Nuclear Science.
